Alberta Scaglione and her twentysomething granddaughter, Jinx, love to spend time-and solve crime-together . . . Ever since Alberta Scaglione inherited her spinster aunt's Cape Cod cottage, she's been enjoying the good life in Tranquility, New Jersey, with her black cat, Lola. But since things are mostly quiet in this town, she finds other things to do-like joining Jinx for morning jogs in Tranquility Park. She has to do something to stay healthy, as long as it doesn't involve Jinx's healthful tofu sausages and gluten-free pasta. But when they stumble across a treehouse hidden in the trees, and a dead body underneath it, they take a detour into solving a murder. Now the Ferrara ladies will have to exercise extreme caution to avoid a permanent decline in their health . . .
